Surface contact/ tube contact temperature measuring transducers THERMASGARD® ALTM 2 - VA
Calibratable THERMASGARD® ALTM 2 - VA tube contact temperature measuring transducer with eight switchable measuring ranges, external sensor, continuous output, rugged housing in V4A stainless steel, with cable gland or M12 connector according to DIN EN 61076-2-101.
The surface-contact transmitter is used for temperature detection on lines, pipes (e.g. cold and hot water) or on heating sections for heating system control.
The sensor is factory-calibrated and can be fine-tuned to ambient conditions by an expert.
